Abstract
A grid simulating muntins for a multi-sheet unit includes a plurality of interconnected vertical and horizontal elongated members. The ends of the elongated members are shaped to engage interior surface of a spacer frame to position the grid within the spacer frame. Shaping the ends of the elongated members eliminates the need for muntin clips.
